***SPOILERS***
This incredibly heart-wrenching movie isn't from the sad backstory of Jane Doe to John Doe but realizing that everything would happen over and over again in a loop, a snake eating its own tail. This follows the convoluted life of a time travelling agent and how she created herself and interacts with herself. Jane was raised in a girls orphanage not knowing her own parents. She has quite the pretentious attitude because she's better than most of her peers and even the boys, both physically and mentally. But in her time women weren't allowed to become astronauts, which was upsetting for Jane but it didn't stop her. During the lengthy examinations, Jane excelled in her work but one day she was defending herself against one of the girls who wanted to fight with her and despite acting in self-defence she was discharged. Soon after Jane starts working as a housemaid and continues her studies in university. Soon she meets a boy and they fall in love. Eventually, she became pregnant. The baby was delivered healthy, but doctors noticed something strange about Jane's body. She had to get her female reproducing organs removed, and had male organs instead. Soon she had to transition into a male with multiple surgeries and had to take testosterone to get a deeper voice but she still had to practice on how to act like a man. Jane changed her name to John and named her baby Jane. In the hospital the baby was kidnapped, by a time traveller (who the next future John) and put into a girl orphanage 20 years in the past. John eventually got a job as a dishwasher, then tried applying again for the space travel, but they saw her as unfit. John tells her life's story to a bartender who she later finds out is a time travelling agent. He has her join and tells her that she could kill the boy who she fell in love with and get away with it. So when John goes to find the boy she bumps into her younger self and they fall in love, and the whole cycle repeats itself again, into an endless loop. I recommend anyone to at least watch this movie twice to spot anything you might have missed, this truly is a masterpiece.

This is taken from the short story "All You Zombies." The dialogue is strikingly similar and some of the ideas were really creative for the time it came out. However, many people may not like this movie because it's complex or has too many plot hole narratives. This, however, is the beauty of this movie. You're meant to feel confused and yet understanding just as the temporal agent slightly goes mad. In the end, she's fighting herself in the ultimate duel to change the course of time. It's a good movie if you can follow it.

not a very good movie, the hype is very overrated. The twist is only because you wouldn't think the story would go in that direction. Not a clever film by any means, just good acting to save an otherwise slow and pretentious film. Probably worth checking out the Heinlein story instead.

Time travel paradoxes are a mainstay of science-fiction and in the Spierig brothers’ Gordian knot of a film, based on a short story by sci-fi great Robert Heinlein, they come fast and merciless. As Ethan Hawke's character jumps back and forth through time in pursuit of his elusive quarry, his temporal leaps begin to take their toll on his mental health—apparently psychoses and dementia are not uncommon in his profession—while the taciturn bar patron he's befriended throws a few ingenious wrenches into the plot and the audience scratches its collective head bloody. Naturally there is a bit of scientific license (a time travel device that fits in a violin case?) and some background information on the furtive X-Files government agency behind the time tampering would have been interesting though hardly germane to the story. But the Spierigs do deliver a rip-roaring head-slapping actioner with far more IQ points than most Saturday night popcorn features—and those clever little clues they toss along the way only reveal themselves in retrospect.

Smart movie. One needs much patience to appreciate a movie like this. It was well-thought of and might need a second viewing to fully understand it. But once you figure out the plot and connect one timeline to another, you'll realize that this is a really good and original movie. Sarah Snook's acting is a good enough reason to watch it.

Don't try to apply any logic to how this type of time travel could actually work, because it all falls apart. If you can let that go, this is an excellent film with a unique twist. I highly enjoyed it.

Awful. Halfway through this film I was completely lost. Read the Wikipedia plot summary and then it all made sense. All of the characters are the same guy. The guy in the beginning, the time traveler who gets blown up by the bomber, is also the drunk guy's father (and mother) and the drunk guy and the bomber. Too far out for me. Logically, it didn't make sense. The first paradox would've occurred after he inseminated himself (don't ask). Unless you're into weird transgender films, this will be too nonsensical to enjoy at all. A waste of two hours. NO fact-checkers were used in the making of this film, and it shows.

Excellent adaptation of the Robert Heinlein short story "All You Zombies". If you read the story beforehand, it will actually help you enjoy and understand the movie too, I think. It's the time-travel logic-twisting concept taken to its limit. Fine acting and the FX not overdone.

Really well done with good acting and a good story....but it still might leave you a little frustrated at the end of it. It's both interesting and contrived at the same time which leave you feeling a bit tricked at the end, but not in a good way...
